2-22 Cell coverage at top of Blewett Pass?

Sorry for the trivial RFI in light of so many serious topics, but does anyone know if there's cell coverage on the top of Blewett Pass Highway?

In particular T-Mobile? I'm doing the Hog Loppet this weekend, and need to coordinate a ride.
Thanks!

At road level, no coverage. I'm not sure up higher, though.

I have tried well up on the on the west side of Diamond head with no luck, you might have a shot before you start the decent to the pass.

Don! No idea on cell coverage but I'll be doing the Hog next weekend as well with a few CBSP patrollers. I'll probably be running sweep. Maybe we can catch up before the race starts, I'll be wandering around trying to look like I know what I'm supposed to do.

Several years ago, I could call both 911 and friends in Cle Elum from the west rim of Table Mtn near the A-frame cabin. My borrowed snowmobile had pooped out. You might have coverage at the saddle between Diamond Head and Table Mtn where the road starts dropping down to Blewett Pass.

In the past I never got cell coverage up there but this year I've had 3 bars at the top of the pass. I haven't checked this year out by Diamond Head though.
